Subcellular localization of enzymes of phospholipid metabolism in Candida albicans.
The intracellular location of various enzymes involved in the metabolism of phospholipids of Candida albicans was studied. Among the biosynthetic enzymes, phosphatidylserine synthetase was found to be localized in the microsomes; choline kinase and ethanolamine kinase were cytosolic; acyltransferase was localized in the particulate fraction and glycerol kinase and phosphatidic acid phosphatase were distributed in both the microsomal and cytosolic fractions. Phospholipase A and phospholipase C were abundant in the microsomes and phospholipase C was also detected in the cytosol. Lysophospholipase and glycerophosphocholine diesterase were distributed mainly in the mitochondria. Lipase activity was also detected in this fungus. Based on the enzymes detected in this study we have postulated pathways of phospholipid metabolism in C. albicans.
